CVE-2022-46824

Local memory corruption via fsnotifier buffer overflow

Published Dec 8, 2022 · Updated Apr 23, 2025

Buffer overflow in IntelliJ IDEA before 2022.2.4 allows local users to cause unspecified impact through the macOS fsnotifier daemon. JetBrains has not published the affected function, the unsafe copy operation, or the untrusted input that overruns the buffer. Reachability requires local execution on macOS; the public record identifies no concrete confidentiality, integrity, or availability consequence.
